Here is the problem. My horse has become untrainable due to the fact that she throws her weight (almost a limp if you will) onto her shoulder when engaged in the trot. Recently she has developed a problem with her canter. She will barely ever even pick it up and when she does she will canter very very collectedly. Many people are mistaking her for a lazy and untrained horse. She upon purchase (a few months ago) was very enthusiastic about her work and very capable. She is a very good horse and I can tell that something is out of line with her.
My horse is a 4 and half year old RPSI mare. She is doing dressage work currently but can jump full courses, but this is her first year with real dressage focus. She has had saddle fit problems. It slides UP onto her shoulders. We have had many saddle fitters say that she has a very normal back that shouldn't be hard to fit. However we cannot find a saddle that works perfectly. Her limping seems to change with different saddle and pad combinations. We have noticed that her hooves are slightly more worn down on the toe rather than the heel which is weird. We have considered a problem with her back but after examining it she doesn't appear to be sore or pained by it when not under tack.
Please help my poor girl so she can return to her training.
